partly in ele- Referringnow more in detailto theidrgwing, thebabys safety pin' comprising the present invention includes an elongated rectangular base portion integrally formed at one end on the upper surface thereof with the hemispherical protrusion 11 having a conical opening 12, sub stantially as illustrated.

The bottom portion 10 at the other end thereof is integrally formed at right angles thereto along the opposite longitudinal edges with the side walls 13 and the arcuate end wall 14, the upper edges of the side walls 13 and end wall 14 being connected by the horizontal top wall 15.

As shown in Fig. 2, the forward end of the top wall 15 is provided with the rectangular cutout 16 which connects with the centrally located, reaiwardly extending slot 17 which terminates short of the end wall 14.

An elongated rectangular upper portion 18 is provided and is adapted to fit downwardly between the side walls or portions 13 within the cutout 16, being integrally formed at this end. with a depending lug 19 having a rounded lower end and an elongated vertical slot 20 therethrough.

The rear vertical edge of the lug 19 is integrally formed with rearwardly and upwardly extending teeth 21 which perspective viewfof the invention A compression coil spring 29 is mounted behind the ridge 27 centrally thereof and has its lower end suitably secured to the'bot'tom portionor jaw 10, the upper end of the compression spring 29 fixedly mounting a horizontal'disc 30 which bears on the rounded lower end of the lug 19,'as shown in Fig. 4, to bring the lower end of the slot 20 into-abutment with the pin 22- As shown in Fig. 3, the bottom portion 10 rearwardly of the spring 29 is formed with a semicircular recess 31 within which is pivotally mounted the lower end of the link 32 by means of the pin 33, an upper end of the link 32 being integrally formed with the forwardly and downwardly extending enlargement 34 having the downwardly h and forwardly extending teeth '35Jwhich are adapted to I mesh with theteeth 21, as shown in Fig. 4. The lever 32 is normally retained in the forward position of Fig. 4 with the teeth 35 in mesh with the teeth 21 of thelug 19 by means of the compression spring 36having its forward end connected tothe lever 32 below and its rear end connected to the end wall 14.

A link 37 positioned within the slot 17 and having an enlarged knob 38 at its upper end is pivotally connected to'the rear end. of the enlargement 34 atone side thereof v to complete the. structure.

lug itself is pivotally mounted between the side walls 13 ,The pin is shown in closed position in Fig. 4. In orderto open the same, ,the'non-operative end of the pin is grasped between the fingers and thumb of one hand with the thumb positioned above the operating knob 38. It will be noted that the opening movement of the upper jaw 18 is prevented by the teeth 35 which are in mesh with the teeth 21 at the lower end of the lug 19 (Fig. 4), these teeth being urged into intermeshing relationship by the compression spring 36. However, upon pressing the knob 38 forwardly and downwardly with the thumb, the teeth 35 will be brought out of mesh with the teeth 21 by the resulting pivotal movement of the lever 32 about pin 33 away from the lug 19. The rear end of the portion 18 is upon pressing the knob 38 downwardly and rearwardly,

the lever 32 will pivot about the pin 33 in the rearward direction and rotate the portion 18 upwardly to the open position, the pin being retained in the open position by the action of the spring 36. In order to close the pin, it is only necessary to press the knob 38 downwardly and rearwardly to disengage the teeth 35 of the lever from the teeth 21 of the lug 19, whereby the jaw 18 may be Patented May 6, 8

the enlargement 34 rotated to a closed position. In use, the corners of the diaper 39 will be pulled together into overlapping relationship and secured between the jaws 18 and 10 with the pin 24 piercing the corners and positioning itself within the conical bore 12 of the protrusion 11. It will be noted that when the pin is attached with pressure, it will not be tight on the babys skin as the cotton diaper gives until the pinis freely displaced therefrom. I

The pin may be made of plastic, steel, aluminum or other similar material and can be made in various colors. such "as blue for boys, pink for girls and so forth. Initials or names may be placed on them as well as other ornamental designs.

The cost of manufacture is relatively small considering the length of time the pin would last. The pin mayalso be, used as a dress fastener and for fastening other garments.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims. 1

The pin 22 may be made adjustable vertically in the side walls 13 by, the provision) therein of the vertically extending slot 40 and the locking collar 41 screw threaded onto the end of the pin and whichwill lock the vertical position of the same within the slot 40, as shown in Fig. 2.
